论文摘要
考虑到$ t $ - 折叠明确的$ t $ t $ - 大约亚组$ a $ a $在某些一阶结构中,有一个可定义的亚组$ h $由$ a $归一化,并包含在$ a^4 $ boundex in $ \ langle a \ langle a \ rangle $中。
Given a $T$-rough definably amenable $T$-rough approximate subgroup $A$ of a group in some first-order structure, there is a type-definable subgroup $H$ normalised by $A$ and contained in $A^4$ of bounded index in $\langle A\rangle$.
